Nesting

The simplest way to create a layout with multiple elements: put one into the other. We've already seen how you can do it with Panels:

Panel(
    Panel(
        Panel(
            "We need to go deeper...",
            height=3,
            width=28,
            style="green",
            box=:ASCII,
            title="ED",title_style="white",
            justify=:center
        ),
        style="red", box=:HEAVY, title="ST", title_style="white", fit=true
    ),
    width=44, justify=:center, style="blue", box=:DOUBLE, title="NE", title_style="white"
)
╔════ NE ══════════════════════════════════╗
║    ┏━━━━ ST ━━━━━━━━━━━━━━━━━━━━━━━━┓    
      +---- ED ------------------+      
      |      We need to go       |      
      |        deeper...         |      
      +--------------------------+      
    ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛    
╚══════════════════════════════════════════╝

okay, nothing crazy here - but we can actually achieve some nice looking layouts with this alone:

import Term: Panel, TextBox

title = Panel(
    "{white bold}This is an {red} important {/red}title{/white bold}";
    width=60, fit=false, box=:DOUBLE_EDGE, style="bright_blue dim", justify=:center
)
summary = Panel(
    "This is a short summary of the content of the next paragraph."^5;
    width=60, fit=false, style="dim", justify=:left,
    padding=(4, 4, 1, 1), title="Summary", title_style="white default"
)

main_text = TextBox(
    "This is a very long paragraph with a lot of text you don't need to read."^10;
    width=60, fit=false, style="bright_blue dim", justify=:left
)

Panel(title, summary, main_text; style="#9bb3e0", subtitle="Techical details",
subtitle_justify=:right, subtitle_style="yellow default"
)
